Thanks for replys guys, soon I will know the answer.. Cut the cats away and made me a qouple of straight pipes. So I will go: Catless headers -> pipes -> FVD Sound version.
After a looong wait IŽll finally have my day at the dyno in the middle of mars this year. Doing the classic 987-airbox/MAF, IPD + 74mm TB + full day mapping on the dyno. Wish me luck! Was aiming for the 996 intake but didnŽt manage.
